我们提倡ThingSpire OS，这是一个基于WebAssembly的新的物联网操作系统，用于云端集成。在设计上，WebAssembly被认为是ThingSpire操作系统中的一等公民，实现物联网设备、边缘和云之间的一致执行。此外，ThingSpire OS通过以较小的占用空间实现基于提前(AoT)编译的WebAssembly运行时，使WebAssembly能够在资源受限的设备上高效执行，无论模块位于何处，都实现了模块间的无缝通信，并利用了几种优化，例如用于存储器隔离和控制流完整性的轻量级可抢占调用。我们实现了ThingSpire操作系统的一个原型，并对其模块间通信性能进行了初步评估。
We advocate ThingSpire OS, a new IoT operating system based on WebAssembly for cloud-edge integration. By design, WebAssembly is considered as the first-class citizen in ThingSpire OS to achieve coherent execution among IoT device, edge and cloud. Furthermore, ThingSpire OS enables efficient execution of WebAssembly on resource-constrained devices by implementing a WebAssembly runtime based on Ahead-of-Time (AoT) compilation with a small footprint, achieves seamless inter-module communication wherever the modules locate, and leverages several optimizations such as lightweight preemptible invocation for memory isolation and control-flow integrity. We implement a prototype of ThingSpire OS and conduct preliminary evaluations on its inter-module communication performance.
